Planning a long US trip before we move — anything to know about doing it by RV?

[AlexGreeneRVF]

We're hoping to spend a few months driving around the US in a rental RV before we settle here — West Coast parks first, then the Southwest in winter. For those who've done a long one-way rental like this, what are the big gotchas on mileage caps and one-way drop-off fees? Any regions or seasons to avoid on that kind of timeline?

Update: we've tentatively booked the rental for March, West Coast first. Our move paperwork is still mid-process — can't tell if a tourist trip right before the visa interview would look odd. Has anyone done a long US trip like this while waiting on immigrant-visa processing? Found this rundown of interview questions while waiting for our appointment confirmation (US visa interview 2026: questions and 10 real stories), but real 'we did exactly this' stories would help more.
